Question on Edelbrock carburetor rebuild kits.

Hello guys I just got a 750 edelbrock performer off of ebay for 60 bucks and I was going to get a rebuild kit for it but I have not gotten one before nor have I ever rebuilt a edelbrock carb. First of all does these kits come with everything to rebuild it too like new condition or is there a few other things to buy with it? Also is it very hard to do a edelbrock rebuild? After a carb is rebuild does it usually make it just like brand new again to some degree or just really helps freshen it up and thats about it. Thanks for any info.
Eric

First off, a carb of of Ebay would make me cringe. There has got to be something wrong with it for them to place it on Ebay. You have one strike against you already, not knowing the history of the carb. You need to get a master rebuild kit and soak that carb in carb cleaner over night. Rinse it in water then blow out all passages with compressed air.

I am not familiar with Edelbrock kits because I run Holley's, but I did mess with quite a few Carter AFB's in high school and we had the best luck with Borg Warner rebuild kits.

Eric, a rebuild kit generally freshens up a carb. I havent found anything that will make them like new. One thing you need to look for in a used carb is warpage that might cause vacuum leaks. Also, clean it very well (like mentioned above) and be sure to blow out all the passages with air.
IMO cleaning it well is more important than the brand of rebuild kit used.

Good luck.

That is what I figured about the rebuild kits. I will try to check for warpage etc but what all do I have to make sure that I take out while I let it soak overnight in carb cleaner? I know I just can't dunk it in as is cause I will have to take the top off and gaskets off I know that much but is there anything inside to have to take out? I planed on a edelbrock kit from summit along with a new accelerator pump and ims screws.

The Edelbrock carbs are nothing more than glorified Carter AFB's and AVS's (depending on the model you have). There are books and videos available on the internet. A quick search with google using edelbrock carburetor rebuild turned up a bunch of things. Here's a couple links to check out.

Hope that helps.

edlebrock carb

the edlebrockk carb is actually one of the easier 4-barrel carbs to rebuild. just be sure the upper secondary butterfly isn't upside down when tou get through, it won't run right, the secondaries won't open up if it is inverted.

The edelbrock is a really easy carb to rebuild, the edelbrock kit comes with the float settings, and you can get the stock jetting from edelbrock's website to make sure no one has changed them from the base setting. you can also verify the spring color relative to vacuum opening from the website, the only problems with a e-bay edelbrock carb, is they are aluminum,so water will destroy them if allowed to sit inside the carb, and the butterfly shafts can become bent with max abuse(look that the butterflies -both primary and secondary,open at the exact same time-meaning the 2 primary butterflies open together,and then the secondary butterflies open together.) other than being corroded or re-jetted to try and make a much larger or smaller carb with the wrong jets,springs or metering rods than the body is capable of, dirt is the only other concern. they are really a quite simple carb that works well in many applications They are an updated version of a carter a.f.b. or the new version is in reality an updated version of a carter wcfb.

Is it manual choke or electric? Here's a link to some repair parts you might need.

Inspect it and when it doubt throw it out...and replace the part.

Hello the carb is manual choke. I took it apart over the weekend and everything looks in good order. I sprayed it down with carb cleaner and let it sit overnight and sprayed it again Sunday. The butterflys look good and they both work as they should. No signs of warpage or anything. I did order a new gasket set, ims screws, and a new acclerator pump. Everything else looked good and I felt they did not need replaced. The floats are in good shape and I have new metering rods and springs to go with it along with my old tuning manual. I shold be good to go after my parts arrive. Thanks guys for help. This was quite easy to rebuild without taking the entire thing apart.
